What is off grid system?
Off-grid solar energy systems are also called stand-alone solar systems. It does not connect with Grid or called Utility. It is very popular and suitable for remote areas where there is no public power or Public power is instable.
It can be for Home applications, Commercial applications and Industrial applications.
The off-grid solar energy system can be 1kW/2kW/3kW/5kW/10kW/12kW/16kW/20kW/24kW/30kW/50kW/80kW/100kW/120kW/150kW/200kW/ Customized off-gid power system
Off-grid system is suitable for areas without grid-connected or unstable grid-connected power.
Off grid system is usually composed of solar panels, connector, inverter, batteries and mounting system.
